Example: Deprovisioning an Object After a Specified Time

You can use the IMVSynchronization.Provision method to trigger deprovisioning on a single connector or multiple connectors to an MVEntry object after a specified time.

Note  This sample only works if you run the management agent containing the remaining connector space object in full-synchronization mode, which is a very time-consuming operation in a large metadirectory.

The following example shows you how to deprovision an object from the metaverse after a specified time. For example, you can use this example to schedule an activity for an object in the metaverse, such as implementing a Time To Live scenario. The example assumes that the metaverse object has two additional attributes: DateofTermination and TimeToLive. These attributes are set during import attribute flow on the metaverse object.

[Visual Basic .NET] 
Public Sub Provision( _
   ByVal mventry As MVEntry) _
   Implements IMVSynchronization.Provision


   ' If the function returns true, the account is expired. Disconnect the 
   ' metaverse object from the connector space.
   If AccountTTLExpired(MVEntry("DateofTermination").Value, MVEntry("TimeToLive").Value) Then
	 MVEntry.ConnectedMAs.DeprovisionAll()
   End If

' Continue with normal provisioning.

End Sub

Public Function AccountTTLExpired(ByVal TerminatedDate As String, _
								 ByVal TTL As String) As Boolean

   ' If the TerminatedDate and TimeToLive attributes contain values, then
   ' add the attributes and compare to the current date. If the current date
   ' is more than or equal to the TerminatesDate and ToLiveTime value,
   ' the function returns true.

   Dim TTLExpired As Boolean = False

   If TerminatedDate.Equals("") Or TTL.Equals("") Then Exit Function

   Try
	Dim StartTTLDate As Date = CDate(TerminatedDate)
	Dim DaysToTTL As Double = CDbl(TTL)
	Dim TimeToLiveDate As DateTime

	TimeToLiveDate = StartTTLDate.AddDays(DaysToTTL)

	If Now >= TimeToLiveDate Then
		 TTLExpired = True
	End If

   Catch
	' Handle exceptions here.

   End Try
   AccountTTLExpired = TTLExpired
End Function
